摘要
Abstract
The availability of the current GNSS RTK algorithm in the city environment is still low and can rarely meet centimeter level positioning accuracy of observation epochs,especially under dynamic conditions.This paper attempts to apply the partial ambiguity fixing algorithm to the city dynamic environment GNSS RTK positioning.This can speed up ambiguity search efficiency and increase the available high precision positioning of the number of epochs.The vehicle borne data in the urban environment is used to verify the availability of the partial ambiguity fixing algorithm.The test results prove that the algorithm can significantly improve the ambiguity fixing rate and increase the number of epochs of cm level positioning in urban environments.关键词
